United States Patent O M' 3,119,351 LliNER AND RETAW'R PANEL Michael .1.Ford, Hartsdale, NX., assigner, by mesne assignments, of one-half tointernational Paper Company, New York, NX., a corporation of New York,and one-half to The Staniey Works, New Britain, Conn., a corporation ofConnecticut Filed May 29, 1959, Ser. No. 816,935 3 Claims. (Cl. 10S-423) This invention relates to a liner and retainer panel, and theinvention is particularly useful in connection with the lining ofrailway boxcars and other freight vehicles.

An object of the invention is to provide a panel which may be secured tothe studs or frame on the interior of the freight vehicle whileutilizing fibrous board material reinforced to provide a sturdy andreadily applied lining wall. A further object is to provide a lining orretainer panel structure of unique construction which may be nailed orotherwise secured to the interior frame of a car while providing asmooth and uniform interior surface for the car. A still further objectis to provide a liner structure in which a metal sheet is supportedwithin fibrous walls of a board for supporting the wall and providing asturdy liner overspace in the freight vehicle wall. Other specificobjects and advantages will appear as the specification proceeds.

The invention is shown, in an illustrative embodiment, by theaccompanyign drawing, in which- FIG. 1 is a broken vertical sectionalview of a railway boxcar equipped with liner material embodying myinvention; FIG. 2, an enlarged broken vertical sectional view, thesection being taken as indicated at line 2--2 of FIG. 1; FiG. 3, abroken plan view of my liner or retainer panel, portions of the panelbeing broken away to show the structure thereof; FIG. 4, a transversesectional detail view, the section being taken as indicated at line 4 4;and FIG. 5, a broken sectional detail view showing a modified form ofpanel board embodying my invention.

In the illustration given in FIGS. l-4, inclusive, A designates arailway boxcar having a bottom wall 10, a top wall 11, an end wall 12and side walls 13. The side walls 13 are provided with spaced verticalstuds 14. B designates my liner or retainer panel secured to the studs14.

The panel B, as shown best in FiGS. 2, 3 and 4, com-l prises twocorrugated cores and 16 bonded to sheets or liners 17 and 13,respectively. On their inner sides, the cores 15 and 16 are bonded byadhesive to a metal sheet 19. The metal sheet 19 is thus supportedresiliently between the corrugated cores 15 and 16 and is adapted toreceive nails 2f) or other fastening means when the panel B is securedto the studs 14, as shown best in FIG. 2.

In operation, the installer places a panel B against the studs 14, asshown best in FIGS. 1 and 2, and drives nails, etc. through the boardinto the studs 14 or other inner frame of the Vehicle. The nail passesthrough the corrugated cores 15 and 16, liners 17 and 1S, and throughthe metal sheet or plate 19 so as to firmly clamp the board against thestud or frame. It is found that the inner portion of the corrugatedboard yields under the nail head so as to be slightly indented, as in atufting operation, and leaves the inner liner surface 17 substantiallyeven throughout so that the nails are not projecting for engagement withthe merchandise carried in the vehicle. At the same time, the metalsheet 19 serves to lock the entire board firmly in position and alsoprovides a reinforcing, weighted carrying support for the portions ofthe board extending between the studs or over openings in the frame.

The metal sheet 19 may be formed of aluminum, aluminum alloy, lightgauge steel, or other metal which provides 3,119,351 Patented dan. 2?,1964 ICC the necessary support while at the same time receiving thenails for fastening the board to the car frame. It is found that themetal sheet not only provides tensile strength for the board but also,mounted as it is between resilient core bodies 15 and 1e, is effectivein cushioning blows from merchandise within the car and in preventingthe corrugated board from breaking or tearing under the impact ofarticles in ordinary shipping conditions. Since the sheet 19 iscoextensive with the panel B, the installer can drive the nails 20readily through the panel and be certain that the nail engages the metalbefore it enters the stud 14.

ln the modification shown in FIG. 5, the metal sheet 19a is supportedbetween fibers 21, the bers being confined on both sides by the liners22 and 23. Preferably the fibers 21 are bound together and to the outerliners by adhesive to form a solid fiberboard and the metal sheet 19oprovides a metal sheet core for the board.

The panels B may be erected one above the other along the sides of thecar, as illustrated in FIG. l, and the adjacent ends may be nailed toform a tight joint, as illustrated best at the top of FIG. 2.

Should one of the panels become damaged, ready repair can beaccomplished by cutting out the damaged portion and using the same as atemplet for forming a repair segment which can be readily nailed inplace. Further, tape can be extended over the adjacent edges of panelsor cut portions of panels to provide ready repair.

While, in the foregoing specification, I have set forth a specificstructure in considerable detail for the purpose of illustrating theinvention, it will be understood that such details of structure may bevaried widely by those skilled in the art without departing from thespirit of my invention.

l claim:

1. In combination with a freight vehicle having an inner frame, a boardpanel secured to said frame and comprising imperforate metal reinforcingmeans embedded within a fibrous body, and liners bonded to the outersides of said fibrous body, said body comprising a corrugated coreinterposed between said frame and means, and nails extending throughsaid panel and into said frame.

2. In combination with a freight vehicle having Vertical studs therein,lining boards nailed to said studs, each board comprising corrugatedcores bonded on the outer sides to liner sheets and bonded on theirinner sides to a central imperforate metal sheet, said metal sheet beingresiliently supported by said cores, the flutes of said cores beingvertically disposed.

3. In a retainer panel for lining freight cars, and the like, animperforate malleable metal sheet sandwiched between a pair ofcorrugated paperboard members, said sheet and members beingsubstantially coextensive whereby a nail passing through an edge portionof one member for securing said panel to a stud, or the like, alsopasses through the other of said members and said sheet, each of saidmembers including a corrugated core disposed immediately adjacent saidsheet and a paper liner adhesively secured to its associated core on theside thereof remote from said sheet, the flutes of both cores extendingin the same direction.
